Hi,
typically that kind of stack dump means that we tried to unlock something that wasn't actually an object (or the heap got corrupted somehow). If its reproducible, you may be able to run with the -X:verbose commandline and get a little more information about what's happening when it's crashing (the faulting instruction and machine register state).
